WASHING- MACHINE.

SPECIFICATION forming part of Letters Patent No. 729,373, dated May 26,1903. Application filed February 3. 1903. Serial Noi 141.643. (Nomodel.)

To a/ZZ whom it nwoy concern/ Be it known that I, IsAAc MARKS, a citizenof the United States, and a resident of the city of New York, borough ofManhattan, in the county and State of New York, have invented a new andImproved Washing-Machine, of which thefollowing is a full, clear, andexact description.

This invention relates to improvements in machines for washing fabrics,such as clothes; and the object that I have in view is the pro vision ofa simple, cheap, and efficient contrivance adapted to be fastened inplace on a suitable vessel and to be operated by hand for the purpose ofsubjecting the fabrics to a rubbing action in order to eliminate dirttherefrom.

Further objects and advantages of the invention will appear in thecourse of the subjoined description, and the novelty will be defined bythe annexedv claims.

Reference is to be had to the accompanying drawings, forming apart ofthis specification,

in which similar characters of reference indicate corresponding parts inall the figures.

Figure l is an end elevation showing my invention applied'to a portionof a washtub or other suitable vessel. Fig. 2 isa plan View of themachine. Fig. 3 is a vertical crosssection through the middle portionYofthe machine, and Fig. 4 is a side elevation looking at that side ofthe machine into which the fabrics are fed.

In carrying my inventionA into practice IY employ a frame A of anysuitable construc` tion. This frame is equipped* on one side withangular brackets B, having clai'n'ping` cylinder E. Said drum may be ofany suitable form, but as shown by the drawings the drum is hexagonal incross-section. The drum is provided with a working face, preferably ofcorrugated form, as at e. This corrugated surface may be provided in anysuitable way on the surface of the drum, but as shown the [iat faces ofsaid drum have slats secured thereto to form a rubbing-surface. With thedrum E cooperates a reciprocatory rubber F, which is disposed above orin overhanging relation to said drum. This rubber has a curved undersurface f, which is covered by a rubbing-surface f@ formed by slats orotherwisethe active surface of the said rubber being presented inopposing relation to the corrugated surface of the revoluble drum. Saidrubber is suspended over the drum by pairs of links g g', which arepivoted at g2 to the rubber. The links g g of each pair convergeupwardly toward a vertically-adjustvable bearing G, each pair of linksbeing pivotally connected at g3 to one of said bearings. Two of thebearings G are employed, and they are fitted kslidably in verticalguides h, attached to upperv cross -bars a' of the frame A, said guidesserving to limit the bearings G to movement in a vertical plane andtoward or from the rubber and the drum. The bearings G are suspended byadjustingscrews H from springs I, said springs being mounted on orconnected with the cross-bars a in any suitable way, so that the springswill yield or give in vertical directions. The screws H have threadedbearings in the ,springs I, the lower ends of said screws beinglooselyconnected in an appropriate way to thevbearings G, while the upper endsof fthe screws are equipped with hand-wheels h for the convenientmanipulationof the screws. h It will be understood that the rubber F issuspended by the screws and the springs in adjustable and yieldablerelation to the revoluble drum, and the pressure eX- erted by thesprings may be regulated by lvarying the position of the rubber withrelation to the drum.

The rubber F is provided at one side with .a longitudinal dependingtrough J, the same being secured to an edge portion of the rubber andhaving its bottom perforated, as shown by Figs. 2 and 4. This trough isladapted to contain a saponaceous substance which is supplied to thefabrics as they are fed into and pass through the space between thecooperating drum and rubber. The rubber is equipped on the opposite sidefrom the trough J with a roller J', loosely journaled in suitablebearings secured to an edge of said IOO rubber, said roller beingarranged to ride upon the fabrics after they pass through the rubber andthe drum. To prevent the fabrics from catching in the space between theframe and the drum, I employ idle guide-rollers K, disposed on oppositesides of the vertical plane of the axis of the drum, said rollers beingjournaled in suitable bearings 7a, attached to lower cross-bars a2 ofthe frame. The drum-shaft D is extended at its ends beyond the sides ofthe frame, said end portions of the shaft being equipped withsprocket-gears m and one end of the shaft having a crank-wheel M, thusmaking provision for the rotation of the drum by hand. The cross-bars a3at the upper part of the frame are extended beyond one side thereof, asshown by the drawings, for the reception of the bearings n, whichaccommodate an intermediate shaft N, the latter being provided withsprocket-gears m', arranged in alinement with the corresponding gears mon the drumshaft, and these gears m m are connected in pairs by endlesssprocket-chains m2, whereby thedrum-shaft and the intermediate shaft aregeared together. however, that other forms of gearing may be used inlieu of the sprocket-chain gearing herein shown. The intermediate shaftN is provided with cranks o, to which are loosely connected the pitmenO, the same having pivotal connection at o' with an edge portion of therubber F, and the rotation of this shaft operates the cranks o in a wayto impart reciprocating motion to the rubber F through the pitmen O. Itwill be understood that the rubber is given a traversing movement overthe drum by the crank-shaft N, which is driven from the drum-shaft D.

In the operation of my invention the clamps B and the frame A are ttedto an edge portion of a vessel C and the screws b are turned for thepurpose of holding the frame A in a stationary position on the vesseland in overhanging relation thereto. The fabrics should be soaked inwater and soap over night or for a suitable length of time, and I preferto attach the machine to the tub or vessel which contains the saturatedclothes. A suitable quantity of soap is placed in the trough J, thescrews H are rotated to properly adjust the rubber with relation to thedrum, and the crank-wheel M is rotated by hand for the purpose ofimparting rotary motion to the drum and reciprocating motion to therubber. The

It will be understood,-

fabrics are introduced by hand below theV trough J and into the spacebetween the opposing faces ofthe rubber and the drum, and said fabricsare caught by the corrugated surfacesof the rubber and drum, so thatthey will be carried over the drum and subjected to the rubbing actionof said drum and the rubber, thus eliminating the dirt and water fromthe fabrics and allowing them to emerge from the machine in a cleancondition. Any suitable receptacle may be placed adjacent to thedelivery end of the machine for the purpose of catching the cleanfabrics.

It is evident that the machine may be operated by power instead of byhand.

Having thus described my invention, I claim as new and desire to secureby Letters Patent- 1. A machine of the class described, comprising aframe, a drum, adjustable bearings slidable on the frame, a rubber,links pivoted to the bearings and the rubber for suspending the latterrelatively to the drum, means for adjusting the bearings, and drivingdevices for said rubber and the drum.

2. A machine of the class described comprising a frame, a drum, springsmounted on the frame, a rubber, means connecting said rubber with saidsprings and suspending said rubber yieldably with relation to the drum,means for varying the tension of the springs, and driving devices forthe drum and the rubber.

3. A machine of the class described, comprisin g a frame, a drum,springs mounted on the frame, bearings slidable on the frame, screwsconnected to the springs and the bearings, a rubber suspended from thebearings, and driving devices for the rubber and the drum.

4. A machine of the class described, comprising a frame, a drum mountedtherein, adjustable bearings guided on said frame, springs supported bythe frame, adjustingscrews connected with the bearings and the springs,a rubber in overhanging relation to the drum, and links pivoted to therubber and to said bearings.

In testimony whereof I have signed my name to this specification in thepresence of two subscribing witnesses.
